TECHNICAL FIELD

The present invention, in some embodiments thereof, relates to a pet protective collar, and in particular, some embodiments relate to a flexible e-collar with stays.

BACKGROUND OF THE INVENTION

When wounded or when a diseased site is present, many animals, for example cats and dogs will instinctively lick or bite at the site of the injury or disease. Repeated licking typically results in slower healing and increased risk of infection. Where animals have undergone a surgical procedure, licking further risks disruption of sutures placed to keep the surgical wound closed while the healing process proceeds. Disruption of a surgical wound is highly undesirable as it subjects the animal to the risk of serious or even fatal internal infections. In any case where a medication is applied, the animal tends to lick it.

As a result, a variety of approaches have been developed to prevent animals from licking or otherwise disturbing wounds or a diseased or injured area while they are healing. For example, one common approach is to use a protective collar known as an “Elizabethan collar” or “E-collar” as they are sometimes called. These collars usually are formed from flexible but relatively rigid materials such as sheets of plastic or cardboard, and are provided in a range of sizes in order to accommodate animals of different size. The E-collar is wrapped around the animal's neck and then secured in place as a means by which to prevent the animal from contacting or otherwise disturbing a wound or site of application of a topical medicament.

One example is provided by U.S. Pat. No. 4,200,057 (Agar), which discloses a method of using a cone-shaped collar made of a semi-rigid material that when secured forms a cone around the animal's neck and which prevents the animal from contacting a region on the animal to which a substance has been applied topically. However, while commonly used, traditional E-collars suffer from a number of limitations that detract from their usefulness.

For example, as discussed above, these collars are usually fashioned from relatively rigid materials. Consequently they are not adapted to folding and take up significant space when on a store shelf, or when stored by an animal owner after purchase and between uses. In addition, the rigid material tends to be uncomfortable for the animal to wear and it can break if bent too far. Further, the rigid material can shatter when subjected to cold temperatures. The rigid materials typically used in E-collars also make it difficult for the animal to eat or drink or get through tight spaces, and the pet is jarred if it bumps into something straight-on. The rigid E-collars can scratch furniture, knock things over and hurt a person. Also, the noise of striking something or even brushing against something can cause stress for the pet.

It is well known in the art that animals dislike the application of the E-collar and will attempt to remove it. This results in increased stress to the animal, and if removed, obviates the utility of the collar to prevent contact of an injured area by the animal, prolonging healing time and increasing the risk of serious infection.

A variety of protective collars have been described, some based on the traditional E-collar design, and others using other designs. For example, U.S. Pat. No. 5,012,764 (Fick & Fair) discloses a cone-shaped E-collar with a custom fittable closure. The device improves upon the traditional collar in that it provides a “one-size fits all” capability. However, the Fick device still suffers from design limitations in that it is a rigid collar that animals dislike.

U.S. Pat. No. 5,469,814 (Moy & Moy) discloses a protective collar that avoids the cone-shape of the traditional E-collar. In the Moy device, the collar comprises a sheet of flexible material sized to cover the entire neck from the back of the mandible to the scapula. Thus, the movement of the neck is restricted such that the animal is prevented from licking or biting at wounds. However, the device is not useful in protecting irritation of injuries to the head as the close fitting design does not prevent pawing of an injury of the head or face.

Similarly, U.S. Pat. No. 4,476,814 (Miller) discloses a donut shaped collar that is wide enough to prevent an animal from turning its head sufficiently in order to lick or chew at an affected area.

Likewise, U.S. Pat. No. 6,244,222 (Bowen) discloses a foam sleeve that like that disclosed in U.S. Pat. No. 5,469,814 covers a region of the animal's neck thereby preventing the animal from bending the neck in order to contact an affected area.

As discussed, the aforementioned E-collars are generally formed from rigid materials, such as plastic, that are uncomfortable and thus not well tolerated by animals. To overcome this problem, some collars have been disclosed that are formed from softer more compliant materials. For example, U.S. Pat. No. 5,133,295 (issued to Lippincott) discloses a collar that comprises two side-by-side rings of soft material, with non-resilient medical padding sewn together along their inner margins. The rings are gathered to form radial pleats that interfere with the ability of the animal to chew or lick affected body parts. However, as the collar could conceivably be bent backwards from the head, it would be possible for an animal to paw at injuries in the head area, again limiting the overall usefulness of this type of collar. Also, a soft e-collar can be easily chewed by the pet due to the inside material being loose.

Referring first to FIGS. 1, 2 and 3, the present invention provides a protective collar 1 effective as a veterinary restraint when fitted on an animal. In this embodiment of the invention the protective collar 1 comprises a first exterior sheet 10 comprising a flexible material having inner and outer arcuate edges 12 and 14 respectively, the edges being generally concentric around a common center and extending between a first end 16 and a second end 18. A second exterior sheet 20 (underneath sheet 10 in FIG. 1) also comprises a flexible material. The second exterior sheet 20 is substantially the same size and shape to enable creating the two sides of the collar with a space for a resilient padding layer 22 as shown in FIG. 2.

The resilient padding layer 22, also of a generally similar shape to the first and second exterior sheets 10 and 20, and is sized to be located between the first and second exterior sheets 10 and 20 as shown in FIG. 2. When assembled, the first and second exterior sheets 10 and 20 and the resilient padding layer 30 form a substantially at least semi-circular shape, as has been shown in FIG. 1. Actually, in order to allow a lot of size adjustability, it is somewhat greater than semi-circular.

The first and second exterior sheets 10 and 20 can be fashioned from a variety of materials including cloth, rubberized cloth, soft plastic and the like. Apart from the physical quality to provide a soft, flexible surface of the finished assembly, the first and second exterior sheets and the resilient padding between then, when formed into the in-use cone shape needs only to be sufficiently rigid and resilient to be self-supporting. The present invention uses materials that are soft and flexible and specifically avoids the use of rigid plastic sheet materials as is commonly found in traditional E-collars. In one particular, it may be desirable to select a soft-surfaced comfortable material for the inside of the collar adjacent to the animals head and neck, and a more rugged material for the outside of the collar. Also, the outside of the collar may be provided in a decorative motif, and may be made of material that is easily cleaned and/or that is resistant to staining

The padding layer 22 may also be fashioned from a variety of materials. The material used in the padding layer 22 should be flexible enough to provide a collar that is softer and therefore more comfortable than traditional e-collar, yet is rigid enough to maintain the desired cone-like shape of the collar when worn by an animal and sufficiently resilient to return to its cone shape when bent. It is preferred that the first and second exterior sheets 10 and 20 be quite flexible with little resilience and resistance to bending, while the padding layer 22 be more resilient such that when they are formed into a unit and applied to an animal in a cone shape it will be sufficiently rigid to maintain its cone configuration yet will easily give when hit or pushed or bent and resilient enough to recover its cone shape. Foam plastic is a good material for use as the padding layer, and a wide range of resiliency, and thickness is available.

In the embodiment of FIGS. 1, 2 and 3 the padding layer 22 comprises a layer of foam sandwiched between the first and second exterior sheets 10 and 20, as shown in FIG. 2. Other materials such as non-woven sheets or like materials may be used to provide a soft sufficiently resilient and rigid padding layer. The first exterior sheet 10 and the second exterior sheet 20 are joined along their peripheries 12 and 14 by sewing.

In the embodiment shown in FIGS. 1, 2 and 3, using separate exterior sheets 10 and 20, they are sewn together along the inner arcuate edge 12 and the outer arcuate edge 14 using conventional hem sewing techniques, using outer hem strips 24 and 26 as shown in FIG. 2, with the padding layer 30 inside. The padding layer 22 may be sewn-in along the inner arcuate edge or the outer arcuate edge, or just retained in the space, the latter being shown in FIG. 2. The outer hem strip 24 (and also hem strip 26) can be made with a reflective surface or a glow-in-the-dark surface for safety and otherwise to easily spot the pet.

Stitching can be used to further strengthen the collar while still allowing it to easily bend on contact and also to provide folding points. Radially extending stitching 28 a, 28 b and 28 c comprising two parallel rows, provides some additional rigidity radially and also provides convenient folding points upon which the collar can be folded for storage or packaging, and further strengthen the integrity of the collar when in use. The preferred stitching is zigzag type or parallel rows of straight stitching that is of a selected width dimension such as about ⅛ inch to about ¼ inch and they extend substantially fully across the width from the arcuate edge 14 to the arcuate edge 12. Examples of collars folded for storage or packaging are shown in FIGS. 6-9 d and are described below. It can be appreciated that the radial stitching lines are placed so that the collar will fold into at least approximately equal segments such that stitch 28 a is about at the center of the collar and stitches 28 b and 28 c are about half way to the beginning of the closure elements. That will allow it to be optimally folded for packaging or storage.

The invention further comprises a means of closure, effective to secure the ends of the protective collar, such that when the ends of the protective collar are secured, the collar forms a truncated cone with an inner opening 30 and an outer opening 32 as shown in FIG. 3. Various means of closure are suitable for use in the invention. In one embodiment hook and loop fastener strips such as Velcro products conveniently secure the ends of the collar to form the desired cone shape as shown in FIG. 3. In the embodiment shown in FIGS. 1, 2 and 3, a plurality of first hook and loop strips 34 are on the exterior sheet 10 (facing up in FIG. 1), in the example, three strips 34 and three sets of tabs 38 and mating plurality of three second hook and loop strips 36 are on the exterior sheet 20 (facing down in FIG. 1). Also, downward facing tabs 40 are sewn onto the end 16 being fastenable to any pair of the tabs 38, or any of the strips 34. As shown in FIG. 1 each end of the protective collar has three strips of fastener material 34 and 36 respectively. This allows the device to be sized appropriately to the animal by allowing a variety of engagement positions for greater or lesser opening neck fitting. Also, with the use of the tabs 40, in addition to providing options for sizing, the edge 16 can be kept from protruding. As few as one strip on one side and two strips on the other side will allow for minimal size adjustability. Using the multiple closure position features, such as the plurality of hook and loop strips a fitted closure can be selected for mating alignment and matching of the outer and inner edges such as shown in FIG. 11. This can be referred to as normal or edge aligned fitting. Also, the plurality of strips and tabs allow for non-edge matched closure, such that for example, the strips may be crossed with respect to each other to be not evenly aligned, so that the shape of the cone can be adjusted, for example, to be narrower at the outside, or wider at the outside or similarly at the inside, such as shown in FIG. 10. This can be referred to as distortion fitting or personalized fitting. The user can conform the shape as desired to conform to the pet's head and neck shape and size. In yet another embodiment snaps are used to secure the ends of the collar.

To maintain the integrity of the collar, the invention provides for a means of securing the first and second exterior sheets to the resilient padding layer. In one embodiment the means of securing the first and second sheets and padding layers comprises laminating or otherwise adhering the padding layer onto at least one of the exterior sheets of flexible material. In another embodiment, the padding layer is laminated or adhered onto both the first and second exterior sheets. Securing the padding layer to the sheets further prevents the animal from separating the layers of the collar and either reducing the effectiveness of the collar or destroying it altogether. In a preferred embodiment the padding layer is laminated or adhered only to the exterior sheet that will be on the inside of the cone, when formed around the animal's head.

Another construction of the protective collar is shown in FIGS. 4 and 5. It is similar generally to the form in FIGS. 1, 2, and 3, but is suitable for smaller sizes, and softer material. In this form a first exterior sheet 40 and a second exterior sheet 42 are sewn together at the outer arcuate edge 44 with a blind hem stitch while the inner arcuate edge 46 has a regular hem stitch with a hem strip 48. Radial stitching 50 does not extend to the outer arcuate edge 44 or to the inner arcuate edge 46 but rather stops short of them leaving a space 56 adjacent the outer arcuate edge 44. There can also be a space 58 adjacent the inner arcuate edge 46. Ends 60 and 62 have near them fasteners such as strips of mating hook and loop fasteners 64 and 68. Also a tab 70 can fasten either to one of the strips 68 or to a patch 72. This construction is preferred for smaller sized protective collars in which a very light weight combination of materials is used such as for cats or kittens For example, the exterior sheets may be sheets of thin or cloth reinforced plastic sheet and the spaces 56 and 58 allow for easy bending. An inner padding 52 can be foam or other material as described above; and it may be adhered to the first exterior sheet or the second exterior sheet or both; preferable at least to the exterior sheet that will form the inside of the cone proximate the animal that is wearing it. This construction is preferred for smaller pets such as kittens. It is more easily flexed so as to make eating easier for the pet.

Conveniently, a number of neck closure means may be provided in order to provide the ability to fashion a protective collar capable of fitting different size animals. As shown in FIGS. 1, 3 and 4, a series of loops 54 are sewn into the hem. These can be made of elastic material so as to stretch to accept the pet's normal collar. Alternatively, a string 62 or other elongated member can be applied through the loops and pulled comfortably around the animal's neck to keep the unit in place. In another embodiment, a drawstring sewn into the inner edge might also be useful to further secure the collar on the animal.

When placed on an animal, the inner opening 30 is adapted to fit securely around the neck of the animal, and the outer opening 32 is of sufficient size to prevent the animal fitted with the protective collar from contacting an area of the body to be protected. If desired, the inner arcuate edge of the collar may be lined with a softer material to increase the comfort of the collar.

Referring to FIG. 12, with the construction as described above, providing a bendable and resilient construction, sufficient to be self supporting, the protective collar can be folded outwardly along its outer margin to provide a cuff 70. This will allow more freedom of movement for the pet's head giving the protective collar more variety of configurations for a wide range of pet sizes.

Notably, these constructions for a protective collar do not have to slip over the head of the pet, but rather can close around the neck.

The exterior sheet or sheets such as sheets 10 and 20 in FIG. 1 can be made as spaces for advertising or personal messages by owners. Also the collar strip strung into the loops 54 can carry advertising or other types of messages. Such messages can relate to beneficial or charitable content or they can be commercial. The collar strip can be reserved with an area in which the owner can implement her own message

The invention further provides a method of using a pet protective collar as described above as a veterinary restraint. The method comprises placing a collar such as that described herein around the neck of an animal, and securing as described. Conveniently, the collar of the invention is suitable to protect an area from contact by the animal's mouth, and yet is comfortable enough to wear that the animal will tolerate the collar.

An additional feature of the invention lies in the ability to fold it into a small package for selling purposes or for the consumer to store it. One folding configuration is shown in FIGS. 7, 8A through 8D. This configuration is most suitable for smaller sizes with very easily flexed soft material such as the version described as illustrated in FIGS. 4 and 5. In this fold configuration the ends 60 and 62 meet and the fold points at 56a and 56b are together, the soft material being able to allow the fold points 56a and 56b to settle together. Another fold configuration is shown in FIGS. 6 and 9A through 9B. This configuration is most suitable for larger sizes with less easily flexed material such as the version described and illustrated in FIGS. 1 and 2. In this fold configuration ends 16 and 18 meet and are held together by the tabs 40 and 38 fastening to a mating strip 34 while the fold points 28 a and 28 b are separate and the fold point 28 b is captured between close to the ends 16 and 18.

The collar is thus suitable for use in a method of protecting a wound from a surgical procedure, an injury that is non-surgical in nature, or to prevent mouth contact of an area to which a topical medicament has been applied.

When applied, it is known that some animals will use their teeth to try to dislodge the collar. This is where adhering the inside layer to the padding is particularly useful because it prevents the animal from finding or creating a fold by biting.

The present invention is directed toward a pet protective e-collar 10 having stays 150 disposed at seams 200 of the collar. In a variant, referring to FIGS. 12-17, the collar 10, is made of flexible material and is configured to fold at seams 200. The seams 200 form a channel 250 sized and shaped to retain flexible stays 150 between a channel side 280 and the collar 10. Optionally, the channel is disposed on an outside surface of one of the sheets of the layered assembly that forms the collar. Optionally, the channel may be formed between the sheets.

The stays 150, shown for example in FIG. 17, are more rigid than the material of the collar 10, are preferably somewhat bendable. For example, the material of the collar 10 may be made of nylon and the stays 150 may be made of bendable plastic. The stays, when connected to the collar have the effect of stiffening the overall shape of the collar and making it more difficult for the collar to be bent. Optionally, the stays are removable. Along the smaller circumference side 300 of the collar 10, the channels have openings 350 to the channels 250 that are securable with a mechanism 400, which in a preferred embodiment is hook and loop (Velcro) disposed inside the channel 250 near the opening 350 and completely across the opening.

In another variant, disposed in front of the opening is an optional piece of loop material 450 for partially occluding the opening 350 to assist in preventing unwanted escape of the stay 150 during use of the collar 10. Loops 500 are also attached to the collar 10 in front of the opening along the circumference 300 of the collar 10. The loops may also assist in preventing escape of the stays 150.

In a variant, referring to FIGS. 18 and 19, the pet protective collar 10 having stays 150 further includes vent holes 29 on front and back sides of the collar 10 that penetrate entirely through the cross section of the collar. Openings of the holes 29 are disposed on outside surfaces of sides of the collar. FIG. 19 is a cross section through line C-C in FIG. 18. The vent holes 29 provide for air flow through the collar 10. Air flow has the advantages of providing cooling for a pet wearing the collar 10 as well as removal of moisture. In a variant, referring to FIG. 20, the vent holes 29 are only on one side of the collar and expose the padding layer 22, but do not penetrate entirely through the collar. In another variant, referring to FIG. 21, the vent holes 29 are on both sides of the collar and expose the padding layer from both front and back sides of the collar, but do not penetrate entirely through the collar.
